Republican presidential candidate Donald Trump on Wednesday defended his decision to toss a news anchor with the Spanish-language Univision network out of a press conference, in his latest tussle with a U.S. television personality.

"I'm not a bully," Trump told NBC in an interview.

On Tuesday, Univision's Jorge Ramos was removed from Trump's news conference in Dubuque, Iowa, after the business mogul-turned-candidate said the journalist was asking a question out of turn.

"He was totally out of line last night," Trump said of Ramos, speaking on NBC's "Today" program.

Ramos, who has been critical of Trump's stance on immigration, said he was waiting for his turn to ask a question on the subject when Trump ordered him out.

"He didn't like my question and when he didn't like my question then he motioned so the one security guard would come where I was and then threw me out of the press conference," Ramos told ABC's "Good Morning America."

The dust-up is the latest involving a television anchor and the outspoken Trump, who also has faced criticism for his war-of-words with Fox News anchor Megyn Kelly following that network's recent Republican presidential debate.

Trump is locked in a legal battle with Univision over the network's recent decision to cancel its contract to broadcast the Miss USA and Miss Universe pageants, co-owned by Trump, after he made controversial remarks about Latino immigrants.

Ramos has been equally vocal about Trump's stance on immigration, telling CNN earlier this month that it was "not only disgraceful but dangerous" and fueling some criticism about his work as an objective journalist.

"He has to explain how he wants to deport 11 million people," Ramos told ABC on Wednesday. "As journalists, we are not only required but we are forced to take a stand and clearly when Mr. Trump is talking about immigration in an extreme way, we have to confront him."
